I dont agree with C. Because it is enough to query Id, since anyways the collection is a list of Sobjects. SO as long as we are querying the ID, it is enough to update any field in the record. So I don't believe this code will run into an error. SO for me the answer is A

You can update fields without querying in SOQL (you can`t get the values from them without querying) So, A is correct

None of the answers are correct. Two interesting things: 1) you CAN update fields without querying in SOQL, but you can`t get the values from them without querying. 2) This snippet makes another error: System.LimitException: Too many SOQL queries: 101

DML limit is 150 so B wouldn't be correct. C seems correct answer....?
